Subscribe to a Server-Sent Events (SSE) stream of agent lifecycle events.
The stream replays retained historical events after the cursor, then
delivers live events as they occur. Events are delivered at-least-once;
clients should deduplicate by event id.
Use the after query parameter or Last-Event-ID header to resume
from a previous position. If the cursor is older than the earliest
retained event, the server returns 410 Gone.
Standard SSE reconnection header. Used as the replay cursor if after query parameter is not provided.
Event ID cursor. Only events with id greater than this value are returned. Takes precedence over the Last-Event-ID header.
Event types to receive. If omitted, all event types are sent.
SSE event stream. Each event is delivered as an SSE frame with id, event, and data fields.
The object type, which is always event.
event "event"
Monotonically increasing event ID. Used as the SSE id field and for replay cursors.
